Title: Amplifier circuit
Inventor: FUKUDA SHINICHI
IPC: H03G3/20
Filed: 1992-12-22
Abstract: PURPOSE:To prevent a deterioration in S/N, and to change over recording and reproducing operations in a short time by controlling the rising and falling of a transistor in a reproducing and amplifier circuit. CONSTITUTION:In a reproducing and amplifier circuit 31, at the time of recording, the emitter voltage of Q4 is increased to almost a power supply voltage by changing over a transistor Q6 to a turning ON state. Also, at the time of reproducing, the emitter voltage of Q4 is decreased to a prescribed potential by changing over Q5 to a turning ON state. In Q5 forming an electrostatic discharging circuit, at the time of reproducing, the emitter voltage is changed over to a saturated state, and the stored charge of a capacitor C4 is discharged in a short time. Also, in a circuit 31, at the time of reproducing, a state between the base and the emitter of Q5 is changed over to a low impedance state by supplying a bias current with Q8, and Q4 is essentially grounded. Consequently, in the circuit 31, an operation is changed over in a short time.
